terminations, even of the names of the fimple bodies, fhould, 
as well as their derivation, be regulated by fome eftablifhed 
For the metals, the termination um has been chofen, 
of murium and fluorium, therefore, which have been chofen 
to reprefent the bafes of the muriatic and fluoric acids, we 
would recommend fuch words as muriogen and fluogen, 
which are derivatives perfeGly confiftent with the modern 
fyftem, and equally expreflive of the character of their ob-

conftitution of the fubftance which it is employed to reprefent, 
without that effort of memory neceflary for the i He a rt on

drogen, which is occafionally found in both conditions, is 
to be afcribed. Sulphur, phofphorus, and carbon, never

ammables, fo that they do not impart to the refulting com- 
pound the name either of a fulphurct, a ipl aghacre or a

oxyd of lead; and as different dofes, or quantities, of oxyge

either by the terms fr, rft oxyd, hgh oxyd, and fo on; or by
